Abstract
Description
Technical Field
[0001] This utility model relates to the field of DC power supply device technology, specifically a high-efficiency ventilation DC power supply device. Background Technology
[0002] A DC power supply, also known as a DC power adapter, is a device that converts electrical energy from one DC voltage to another. Its core function is voltage conversion and regulation, achieved through an internal DC-DC converter. A DC-DC converter transforms the input DC voltage into the desired output DC voltage; this process typically involves three main steps: filtering, conversion, and output.
[0003] When connected to high-power electrical devices, existing DC power supplies inevitably generate heat due to their high output power. Common power supplies rely solely on passive heat dissipation through ventilation holes, which is ineffective. Furthermore, existing DC power supplies are poorly integrated, often consisting of multiple individual electrical components, resulting in a large and inconveniently portable assembly. Therefore, a more efficient and well-ventilated DC power supply is needed to meet these needs. Utility Model Content
[0004] The purpose of this invention is to provide a high-efficiency ventilation DC power supply device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency ventilated DC power supply device, including a mounting box; the mounting box contains a power supply device, a heat dissipation device is provided on one side of the mounting box, a setting panel and a display screen are provided on one side of the mounting box, and a heightening pad is provided at the bottom of the mounting box;
[0006] Preferably, the power supply device includes a mounting circuit board, which is fixedly installed inside the mounting housing. A transformer is fixedly installed on the mounting circuit board, a plurality of capacitors are fixedly installed on the mounting circuit board, and a discharge tube is fixedly installed on the mounting circuit board.
[0007] Preferably, a communication board is fixedly mounted on one side of the mounting circuit board, the communication board is electrically connected to the mounting circuit board, and a communication interface is fixedly mounted on the communication board.
[0008] Preferably, the mounting housing has several interface slots on one side, one of which has a main power interface fixedly installed. The main power interface is electrically connected to the mounting circuit board, and the communication interface is fixedly installed in the interface slot.
[0009] Preferably, the heat dissipation device includes a fan, which is fixedly installed in the mounting housing on the side away from the display screen. The mounting housing has a first ventilation opening on the side near the fan, and a protective mesh is fixedly installed in the first ventilation opening.
[0010] Preferably, a heat sink is fixedly mounted on the mounting circuit board, and the heat sink is mounted on the side of the fan.
[0011] Preferably, the mounting housing has first ventilation holes on both sides near the display screen, and a second ventilation hole on the bottom of the mounting housing near the display screen.
[0012] Preferably, both the setting panel and the display screen are electrically connected to the mounting circuit board.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] (1) This utility model connects to external devices through the main power interface and the communication interface. The power supply is transformed and output through the transformer on the mounting circuit board. The capacitor can filter and stabilize the input current, thereby ensuring the stability of the output current. The discharge tube plays the role of overvoltage protection. When the mounting circuit board is subjected to excessively high voltage, it conducts to absorb the overcurrent generated by the overvoltage and protect the circuit from damage. By integrating functional components on the mounting circuit board, the size of the device can be reduced, the integration of the device can be improved, and the cost of a single component can be reduced.
[0015] (2) When the equipment is in use, the fan rotates to generate airflow. The fan draws the airflow out of the installation box and discharges it through the first ventilation port. The airflow enters the installation box through the first ventilation hole and the second ventilation hole. After passing through the heat sink, the heat on the heat sink is carried away and discharged by the fan, thereby achieving active heat dissipation, improving the heat dissipation performance of the equipment, and enabling it to be used stably under high power output.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] Example 1: Please refer to Figure 1-5 This utility model provides a technical solution: a high-efficiency ventilated DC power supply device, including a mounting box 1; in order to improve the heat dissipation of the DC power supply device and reduce its volume, a power supply device 2 is provided inside the mounting box 1, a heat dissipation device 3 is provided on one side inside the mounting box 1, a setting panel 4 and a display screen 5 are provided on one side of the mounting box 1, and a raising pad 7 is provided at the bottom of the mounting box 1. The overall volume of the device is reduced by the integrated circuit components of the power supply device 2, and the stability of the device is improved when it outputs high power by actively dissipating heat through the heat dissipation device 3.
[0024] To achieve a smaller device size for the integrated circuit board, the power supply unit 2 includes a mounting circuit board 20, which is fixedly installed inside the mounting housing 1. A transformer 21, several capacitors 22, and a discharge tube 23 are fixedly installed on the mounting circuit board 20. A communication board 24 is fixedly installed on one side of the mounting circuit board 20 and is electrically connected to it. A communication interface 26 is fixedly installed on the communication board 24. Several interface slots 6 are provided on one side of the mounting housing 1. A main power interface 25 is fixedly installed in one of the interface slots 6 and is electrically connected to the mounting circuit board 20. The communication interface 26 is fixedly installed in the interface slot 6. The control panel 4 and the display screen 5 are both electrically connected to the mounting circuit board 20. In use, the main power interface 25 and the communication interface 26 are connected. For connecting external devices, the main power interface 25 is the main power connection interface, and the communication interface 26 is the communication interface. The communication interface 26 communicates with the mounting circuit board 20 through the communication board 24 to transmit data. At the same time, the communication interface 26 on the communication board 24 can be expanded to have multiple interfaces, allowing it to connect to different devices and modules, thus broadening its application range. The power supply is transformed by the transformer 21 on the mounting circuit board 20 before being output. The capacitor 22 can filter and regulate the input current, thereby ensuring the stability of the output current. The discharge tube 23 plays an overvoltage protection role. When the mounting circuit board 20 is subjected to excessively high voltage, it conducts to absorb the overcurrent generated by the overvoltage and protect the circuit from damage. By integrating functional components on the mounting circuit board 20, the size of the device can be reduced, the integration of the device can be improved, and the cost of individual components can be reduced.
[0025] Example 2: Figure 2-4To improve the heat dissipation performance of the equipment, the heat dissipation device 3 includes a fan 34, which is fixedly installed inside the mounting housing 1 on the side away from the display screen 5. A first ventilation opening 32 is provided on the side of the mounting housing 1 near the fan 34, and a protective mesh 33 is fixedly installed inside the first ventilation opening 32. A heat sink 35 is fixedly installed on the mounting circuit board 20, and the heat sink 35 is installed on one side of the fan 34. First ventilation holes 30 are provided on both sides of the mounting housing 1 near the display screen 5, and a second ventilation hole 31 is provided at the bottom of the mounting housing 1 near the display screen 5. When the equipment is in use, the fan 34 rotates to generate airflow, which cools the mounting housing... Airflow is drawn out from inside body 1 and discharged through the first vent 32. Airflow enters the mounting housing 1 through the first vent 30 and the second vent 31. After passing through the heat sink 35 and carrying away the heat on the heat sink 35, it is discharged by the fan 34. The heat sink 35 is fixedly connected to the mounting circuit board 20. The heat sink 35 is made of a material with good thermal conductivity, which enables the heat generated when the mounting circuit board 20 is working to be quickly transferred to the heat sink 35. The fan 34 accelerates the airflow to carry away the heat, thereby achieving active heat dissipation, improving the heat dissipation performance of the equipment, and enabling it to be used stably under high power output. The other features are the same as in embodiment 1.
[0026] The working principle is as follows: During use, external devices are connected via the main power interface 25 and the communication interface 26. The main power interface 25 is the main power connection interface, and the communication interface 26 is the communication interface. The communication interface 26 communicates with the mounting circuit board 20 via the communication board 24. Simultaneously, the communication interface 26 on the communication board 24 can be expanded with multiple interfaces, allowing it to connect to different devices and modules, thus broadening its application range. The power supply is transformed by the transformer 21 on the mounting circuit board 20 before output. The capacitor 22 filters and stabilizes the input current, ensuring the stability of the output current. The discharge tube 23 provides overvoltage protection; it conducts when the mounting circuit board 20 experiences excessively high voltage, absorbing the overcurrent generated by the overvoltage and protecting the circuit from damage. Integrating functional components onto the mounting circuit board 20 reduces the size of the device, increases its integration, and reduces the cost of individual components. When the device is in use, the fan 34 rotates to generate airflow. The fan 34 draws the airflow out of the mounting housing 1 and discharges it through the first vent 32. The airflow enters the mounting housing 1 through the first vent 30 and the second vent 31. After passing through the heat sink 35 and having its heat carried away by the heat sink 35, the airflow is discharged by the fan 34. The heat sink 35 is fixedly connected to the mounting circuit board 20. The heat sink 35 is made of a material with good thermal conductivity, which allows the heat generated by the mounting circuit board 20 to be quickly transferred to the heat sink 35. The fan 34 accelerates the airflow to remove the heat, thereby achieving active heat dissipation, improving the heat dissipation performance of the device, and enabling it to operate stably even under high power output.
